Truth and Error: The Opening of the Scriptural Truth of the Doctrines of Grace by Horatius Bonar and published by Classics.
"These letters are little more than fragments. They do not aim at a complete statement of the truth, or a systematic arrangement of it. It is only a few important points that they touch. To have extended them and embraced a wider range of doctrine would not have suited my design. I wished to warn you against some of the prevailing errors of the time, lest you, being “led away... from your own steadfastness” should follow after the “diverse and strange doctrines” of these last days. So it was necessary to dwell upon those errors which have been most prominently advanced, and to open up those truths which have been most perverted and denied. My appeal is to the Word of God. “What are the reasonings, or opinions, or inferences of men? What is the chaff to the wheat?” saith the Lord. Let the Bible decide each question. It is for this that I have appended to each letter a selection of passages at length."
